yep, you just have to make sure that you place all the blueprints down, BEFORE one of them completes. Also, the same goes for shipyards, one the military stations are down, quickly click the build shipyard icon, place blueprint and move to next station, as seen from screenshot, i had 6 stations, and 6 shipyards. but if your not quick the button will be greyed out.

"Ah yes, another thing. The cheat is not working for the AI, but the AI is cheating like hell by default. Eg it does not have any unit limit and it can build Destroyers without shipyards so no idea how is it getting it's army."
